The capacity of a closed cylindrical ves...

The capacity of a closed cylindrical vessel of height 1 m is 15.4 litres. How many square metres of metal sheet would be needed to make it?

Text Solution

Verified by Experts

Volume=15.4 liters
`pir^2h=15.4*10^(-3)m^3`
`r^2=49*10^(-4)m^2`
`4=7*10^(-2)m`
TSA of cylinder=CSA +2BA
=`2piRh+2pir^2`
=`2pir(r+h)`
=`2*22/7*7(1+0.07)m`
